Changing times call for new experiences. I think Alexander's quote speaks to that fact. At its very core, I thin the meaning of this quote is telling us to at least try, make the attempt at doing. You don't have to be the first to try something, just don't be the last. If you have a mission in life, a purpose, or a passion, making the attempt at bringing it to life is important. Do not wait and let the world pass you by. The time is now!
